CAOHC EXAM
Five hassle audiograms that require professional supervisor - ANS--STS
-Recordable STS
-Reporting ache, dizziness.
-Asymmetric HL
-inconsistencies
dB is - ANS-amplitude/ loudness/ intensity
Follow up process after STS - ANS--notify worker in writing within 21 days
-can retest inside 30 days - if no STS and uncovered to less than 90 dBA TWA then can
discontinue use of HPD
-must b geared up, trained and use HPD
how to state regulations vary from federal? - ANS--extra strict bc has to b accredited and
monitored via OSHA
Hz is - ANS-frequency / pitch
Parts of audiometer - ANS--selection for frequency
-dial for dB
-interrupter transfer to present tone
-continuous or interrupted tone choice switch
-selection for R/L ear
-earphones
Process for locating audiometric threshold - ANS-start at a thousand w 30 dB if no hear cross as
much as 50 if still no longer cross as much as 60 , if listen do the down 10 up 5 till find 2/3
ascending yeses then visit 500 then one thousand....
Required components for listening to conservation schooling - ANS--consequences of noise on
our hearing
-motive of HPD- pros, cons, attenuation, choice, fitting, use, care
-cause of checking out and explanation of trying out
-noise controls used for your place of work
-employees right to get admission to statistics
Three strategies of healthy verification for HPDs - ANS--field microphone in actual ear (F-MIRE)
-loudness balancing
